I'm sorry to hear that the game crashes on your pc.
Could you provide us the log file? You can find it under ~/.config/unity3d/Just2D/Drova/Player.log
Then send this file to info@just2d.com so we can examine the problem. You can also join our discord (https://discord.gg/9B2NAZyrgq) and write me directly (Johannes) with the log file.
Thanks in advance. :)
